Take this medication by mouth with a full glass of water (8 ounces / 240 milliliters) unless your doctor directs you otherwise, usually once daily. Do not lie down for at least 10 minutes after taking this drug. To prevent stomach upset, take this medication with food, milk, or an antacid.
Do not crush or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking.

Do not increase your dose or take it more often than prescribed. Discuss the risks and benefits with your doctor or pharmacist.
Take this medication regularly in order to get the most benefit from it. Remember to take it at the same time each day. It may take up to 2 weeks of regular use before the full benefits of this drug take effect.
